1 Claim. 1

The invention herein disclosed relates to sewing machine lights and the main purposes of the invention are to combine the light and the motor and to utilize the motor as a means for supporting the light fixture and for carrying and concealing the combined wiring for the lamp and the motor.

Special objects of the invention are to provide such an adapter construction in a simple, inexpensive form readily applicable to existing motor and lamp units and adapted to form an ornamental as well as a thoroughly practical and useful addition to the motor.

Other special objects of the invention are to provide the adapter in a form enabling it to be used with different kinds of motors and lamp fixtures and to be otherwise, as nearly as possible, universally useful with motors and lamps of conventional design.

Other desirable objects attained by the invention are set forth or will appear in the course of the following specification.

The drawings accompanying and forming part of the specification illustrate a present preferred embodiment of the invention. Structure, however, may be modified and changed as regards this disclosure, all within the true intent and broad scope of the invention as hereinafter defined and claimed.

Fig. l in the drawing is an elevation showing a motor as usually mounted on the back of a sewing machine head and equipped with the new adapter carrying the light fixture;

Fig. 2 is an enlarged broken longitudinal sectional view through the adapter and end plate of the motor on which it is mounted;

Fig. 3 is a vertical sectional view through the adapter, on substantially the plane of line 3-3 of Fig. 2, looking toward the motor end;

Fig. 4 is a broken horizontal sectional view through the adapter on substantially the plane of line 4- of Fig. 2.

Fig. 5 is a broken sectional view showing particularly how the wiring for both the lamp and the motor is carried through the adapter and motor casing.

Fig. 1 shows a motor 5 of conventional design mounted in the usual drive position on the back of a sewing machine head.

In this same view the lamp supporting fixture or socket is shown at 6 at the back of the sewing,

machine arm, in position to illuminate the work on the bedof the machine.

The new adapter which is indicated generally at 1 in Fig. l, is in the nature of a hollow goose neck structure closely fitted to and rising from the end of the motor and carrying at the upper end a seat for mounting the light fixture.

Specifically the adapter is shown as made up in two parts, a hollow, arcuate cap or crown piece 8 arched to fit over the top of the motor end head 9, and a tubular barrel section It fitting over the open end of the first piece and having a de pendent flange portion ll engageable over the motor end plate 9.

Screws l2 extending through the dependent flange portion I i into nuts or screw seats located at the inner side of this plate, hold the adapter in its fitted relation over the top and end of this plate.

Long screws I3 extending from the end cap portion 8 through the intermediate barrel portion so into seats 14 in the base of the light fixture i3, serve to secure all these parts together, as will be evident from Figs. 2 and 4.

The two parts, 8 and it of the adapter, may have interfitting shoulder elements 15 at their meeting edges to maintain them in properly aligned relation. These parts may be shaped to fit different motor heads and difierent lamp fixtures, and by proper interchanging of such parts they may be made to fit conventional types of motors and lamp sockets now in general. use.

The two interfitting members of the adapter also may taper upwardly as indicated in Fig. 3, from a relatively wide supporting structure based on the motor to a smaller diameter portion represented by the lamp socket. This somewhat pyramidal form gives desirable ornamental effect as well as strengthening the structure.

The height of the gooseneck portion extended up from the motor is sufficient to support the lamp at a proper elevation above the bed, and all this portion being tubular inform provides a conduit for carrying and concealing the wiring for the lamp and partly for the motor.

Fig. 5 shows how the wiring may arranged. with a supply cord it equipped with an. attachment plug i i for engagement a wall outlet, this cord extending through one i. ening it in the motor and head and out throw anoth r opening it? enclosed within the hollow gooseneclr. up to the terminals iii, 2%, of the lamp socket. This puts the lamp in a supply circuit controlled by the switch 22 of lamp fixture so that the light may be on or on at any entirely independent of the motor.

A second cord circuit is provided toe-Liable the motor to be controlled independently of the lighting circuit. This second cord circuit is shown as having one conductor, 23, extending from one terminal, 2 I, of the lamp fixture to the knee switch or other control box 24, and the second conductor, 25, extending from the control box to a terminal 26 in the adapter. This second, motor control cord may .extend through the same openings in the end head otthe motor as the first cord, so as to be covered, concealed and protected in the same manner. 7

The rest of the motor control, circuit is shown as a conductor 21 extending'from the-common terminal 26 to the field 28 of the motor, and from the opposite side of {the field-.by. conductor 29 to the other lamp fixture terminaliw. 'F'Ihe motor and lamp are thus in parallel circuits re-.

ceiving current from the same power source and controllable each independently --of ,the other.

The two hollow compansion parts of the adapter may be produced at low cost in. molded plastic of desirable insulating and aesthetic quali;ties.

T a r n ement o 1.:th n amp -winn disclosed is especially desirable as keeping this wiring; protected; and out ofasight with the only exposedmortions; these two ;,lengths:;ofcord. ex-
